To restrict a substitution to the first 100 lines, youcan use:If you know exactly how many lines are in a file, you can explicitly state that number to perform the substitution on the restof the file.
Dashes give greater emphasis to parenthetic material than do commas or parentheses. If the parenthetic material contains internal punctuation or forms a complete sentence, the commas that might have been used to enclose it should be replaced by dashes or parentheses, depending on the degree of emphasis desired or the closeness of the relationship to the rest of the sentence. Parentheses are generally used to enclose material more remote from the main thrust of the sentence, dashes for material more closely related:
Parentheses are among the most useful and versatile punctuation marks in the English language. They can be used effectively in both formal and casual writing, and the rules surrounding parentheses allow writers to use them for a variety of purposes.
But parentheses should be used conservatively and with discretion. Today we’ll look at the many ways in which these punctuation marks come in handy and explore the rules for usage and formatting.
The legacy command line style works, but has the same problems that plagued IMversion 5 (see above). All settings are applied before the first read, and all the operatorsare just saved away to be executed when the first image is read (and only onthe first image). There is also no guarantee of the order of multipleoperators will be the same as the order you give, though it is likely theywill be applied in that order.
The form specifies a zero-width negative lookahead. In order for it to succeed, the pattern inside must fail to match at the current position. The current position is not advanced before matching the sequel. can contain capturing parentheses, but backreferences to them only make sense from within itself. Backreferences to these capturing parentheses from elsewhere in the pattern always return undefined because the negative lookahead must fail for the pattern to succeed. For example,
An is either a character or an integer. An is used to denote the interpretation of a escape sequence: a character means that the escape sequence is interpreted as the character , while an integer means that the escape sequence is interpreted as a backreference to the set of capturing parentheses.
A is an ordered pair where is an integer and is an internal array of values. are used to represent partial match states in the regular expression matching algorithms. The is one plus the index of the last input character matched so far by the pattern, while holds the results of capturing parentheses. The element of is either a String that represents the value obtained by the set of capturing parentheses or undefined if the set of capturing parentheses hasn’t been reached yet. Due to backtracking, many may be in use at any time during the matching process.
The function is intentionally generic; it does not require that its this value be a Date object. Therefore, it can be transferred to other kinds of objects for use as a method. However, it does require that any such object have a method. An object is free to use the argument to filter its stringification.
ECMAScript requires the ability to specify digit years (extended years); approximately years, either forward or backward, from 01 January, 1970 UTC. To represent years before or after , ISO 8601 permits the expansion of the year representation, but only by prior agreement between the sender and the receiver. In the simplified ECMAScript format such an expanded year representation shall have extra year digits and is always prefixed with a + or – sign. The year is considered positive and hence prefixed with a + sign.
If is not an integer between 2 and 36 inclusive throw a RangeError exception. If is an integer from 2 to 36, but not 10, the result is a String representation of this Number value using the specified radix. Letters - are used for digits with values 10 through 35. The precise algorithm is implementation-dependent if the radix is not 10, however the algorithm should be a generalisation of that specified in .
When the method is called with one argument , it returns a Number other than NaN that represents the result of a locale-sensitive String comparison of the this value (converted to a String) with (converted to a String). The two Strings are and . The two Strings are compared in an implementation-defined fashion. The result is intended to order String values in the sort order specified by the system default locale, and will be negative, zero, or positive, depending on whether comes before in the sort order, the Strings are equal, or comes after in the sort order, respectively.
Every built-in Function object described in this clause—whether as a constructor, an ordinary function, or both—has a property whose value is an integer. Unless otherwise specified, this value is equal to the largest number of named arguments shown in the subclause headings for the function description, including optional parameters.
